### Calling Sequence

  `show_nodes(nodes,[sup])`

### Parameters

- `nodes`: row vector of node numbers
- `sup`: string, superposition flag

### Description

`show_nodes` highlights the set of nodes `nodes` of the displayed graph in the current edit_graph window. If the optional argument `sup` is equal to the string 'sup', the highlighting is superposed on the previous one.

### Examples

    ta=[1 1 2 2 2 3 4 5 5 7 8 8 9 10 10 10 11 12 13 13 13 14 15 16 16 17 17];
    he=[2 10 3 5 7 4 2 4 6 8 6 9 7 7 11 15 12 13 9 10 14 11 16 1 17 14 15];
    g=make_graph('foo',1,17,ta,he);
    g('node_x')=[283 163 63 57 164 164 273 271 339 384 504 513 439 623 631 757 642];
    g('node_y')=[59 133 223 318 227 319 221 324 432 141 209 319 428 443 187 151 301];
    show_graph(g);
    for i=2:3:g('node_number'), show_nodes([i]); end;
    for i=1:3:g('node_number'), show_nodes([i],'sup'); end;
